Fertilizer treatments were non- fertilized and fertilized with granulated lime stone. Precommercial thinning treatments were no-release, spaced, row thinning with crop tree release, and row thinning with no crop tree release. Data include treatment information as well as tree species, diameter at breast height, height, height to crown base, and crown width measured periodically since 1976. Data are currently available through 2008.
